When I heard it, I envisioned the Autobots retracting to a nearby cave, where Bumblebee, Ironhide, Arcee and Sideswipe would fight the Decepticons while Ratchet puts Jetfire's parts arround Optimus, whos layed in the ground. Jolt energizes them, and they attach to Optimus body. Then, Ratchet places the Matrix inside Prime's chest, and he comes back to life.
